The Internet goes mobile
! 1999: SMS generates
10% revenue of an
operator
! Early 2000: WAP
deployed in most of the
networks
! End 2000: GPRS starts
commercial service

Internet-on-Air
The Evolution Target of Mobile Networks and Internet
Evolution Path of Mobile Networks:
y Use IP transport in the backbone.
Mobile Networks
y Transport voice & data over IP.
y Push IP into the RAN.
y Terminate IP in the mobile host.
Internet-on-Air
Evolution Path of the Internet:
y Enable wireless access.
y Support user & terminal mobility.
y Go beyond “Best Effort”.
Internet
y Provide Security and AAA.

Characteristics of the IoA Network
! End-to-End IP, Internet compliant (IETF, W3C, DMTF).
!
Enhancements where necessary to enable mobility. Design is based on IPv6.
! Support end-to-end multi-media communication
over heterogeneous networks.
! Use TCP/IP as a common framework for multimedia communication.
! Enable global mobility.
! Access over many different networks (wireless & wireline).
! Interworking with existing (legacy) networks.
! Provisions for allocation and management of network resources.
! Voice is only one possible application, although an important benchmark.
Clear split between transport network and applications.
